In what is being hailed as the biggest breakthrough since the 1960s in treatment for latent tuberculosis — noninfectious TB without symptoms — researchers said Monday that weekly doses of a cocktail of antibiotics can cure the infection in only three months as effectively as the standard treatment of daily drugs for nine months. By reducing the number of pills and shortening the time required for therapy, the new regimen increased the proportion of patients who completed treatment from 69% to 82%. By increasing the success rate of therapy, the regimen should reduce spread of the disease and the risk of inducing resistance to TB drugs, experts said.

Yet another study has found stuff you don't want to eat in stuff that you eat. On April 15, scientists reported that the meat bought at supermarkets is often contaminated with Staphylococcus aureus bacteria that are resistant to antibiotics used to fight human disease. The study, published in the journal Clinical Infectious Diseases, found staph on 47% of 136 samples of beef, chicken, pork and turkey from 26 grocery stores in five U.S. cities. Of those bacteria, 96% were resistant to at least one type of antibiotic and more than half were resistant to at least three.

An antibiotic developed by a San Diego firm received a government panel's backing as a treatment for diarrhea caused by increasingly common bacterial infections often acquired in hospitals and nursing homes. The panel of outside experts convened by the Food and Drug Administration voted 13 to 0 that fidaxomicin, marketed under the trade name Dificid by Optimer Pharmaceuticals Inc., is safe and effective in combating symptoms associated with Clostridium difficile , also known as C. diff . The unanimous vote endorsed the FDA's preliminary findings and increases the chances that the agency will approve fidaxomicin.

After reports that a dangerous drug-resistant bacterium, carbapenem-resistant Klebsiella pneumoniae , or CRKP, had spread to at least 356 patients in Southern California last year, Times staff writer Molly Hennessy-Fiske spoke with Dr. Kavita Trivedi, medical epidemiologist with the California Department of Public Health's Antimicrobial Stewardship Program Initiative, about what can be done to reduce the spread of such drug-resistant "superbugs....

A dangerous drug-resistant bacterium has reached Southern California healthcare facilities, according to a study released Thursday by Los Angeles County public health officials. Researchers found 356 cases of carbapenem-resistant Klebsiella pneumoniae , or CRKP, at healthcare facilities in Los Angeles County, mostly among elderly patients, said author Dr. Dawn Terashita, a medical epidemiologist with the county Department of Public Health. "We think that this is increasing," Dr. Jonathan E. Fielding, the county's public health chief, said of the infections.

An experimental antibiotic called fidaxomicin is more effective than the gold standard drug vancomycin at reducing recurrences of the often-lethal bacterial infection Clostridium difficile , Canadian and American researchers reported Wednesday. The drug's manufacturer, Optimer Pharmaceuticals Inc. of San Diego has applied to the Food and Drug Administration for accelerated approval of the antibiotic, and the agency is expected to reach a decision by the middle of this year. If the drug is approved, it would represent the first new drug to treat C. difficile in at least a decade and "an important advance" in treating the infections, according to Dr. Herbert L. DuPont of the University of Texas School of Public Health in Houston.

Calcium channel blockers prescribed to lower blood pressure and macrolide antibiotics to treat infections can combine to sharply reduce blood pressure in the elderly, leading to an increased risk of hospitalization and other problems, Canadian researchers reported Monday. The combination of drugs probably reduces blood pressure in younger patients as well, but represents a bigger risk in the elderly, who are already at increased risk of falls, said Dr. David Juurlink of the Sunnybrook Research Institute in Toronto, who led the study reported in the Canadian Medical Assn.

The medical consensus on whether to give antibiotics to young children with ear infections has been swinging from one extreme to the other as conflicting clinical trials have pushed pediatricians first toward widespread use of the drugs, then toward a "watch and wait" approach in which most infections seem to clear up on their own. Two new trials reported Wednesday in the New England Journal of Medicine are nudging the pendulum back toward treatment...

I suffer from digestive upset when taking antibiotics, and I'd like to counter that with the probiotic bacteria in yogurt. Does taking antibiotics with yogurt affect absorption of antibiotics? It depends to a certain extent on the antibiotic, but many should not be taken within a few hours of yogurt or other calcium-rich foods. That includes antibiotics in the tetracycline family and drugs such as ciprofloxacin and norfloxacin, but not ofloxacin. Fruit juice fortified with calcium also can interfere with antibiotic absorption.
